1. A measurement device comprising:
an imager that captures a target including a pallet and a load, the pallet including a reference target;
an image processing unit that extracts a specific region in the reference target and a region of the load based on image data of the target captured by the imager; and
a calculator that acquires first coordinate information indicating 3D coordinates associated with the image data and standard load form structure information indicating a structural dimension of a standard load form of the pallet associated with coordinates of the specific region, and calculates protruding lengths of the load protruding from the pallet based on the specific region, the region of the load, the first coordinate information, and the standard load form structure information,
wherein
the image processing unit acquires output data obtained by inputting, as input data, the image data of the target captured by the imager to a first machine learning model subjected to training by using, as training data, image data of the pallet having the reference target and data indicating the specific region in the reference target, to extract the specific region in the reference target.
